Bibliometric analysis of core journals which publish articles of physical therapy on aging.

OBJECTIVE: Increase in population's longevity has led to considerable efforts worldwide on physical therapy aging research. The aim of this study is to identify which are the main scientific journals, as well as the most productive authors, institutions and keywords related to the journals, that have published about physical therapy and aging. METHODS: Original articles published from 1990 to 2014 were retrieved from the bibliographic database Science Citation Index Expanded of Web of Science Core Collection. After standardization of the bibliographic information, a series of bibliometric indicators was obtained regarding authors, institutions, citation and keywords of the core journals using bibliometric software. The PAJEK network analysis program was used for graphic representation. RESULTS: A total of 2,237 original articles are included in this analysis. The number of identified journals is 573, with an average growth of publishing journals throughout the studied period of 9.41%. Bradford's distribution shows 12 core journals, out of which 41.67% have published constantly all throughout the 25-year period, being the most productive one Physical Therapy. Fritz, Julie M is the most productive author, and University of Sydney the most productive institution. The keyword exercise is used in an outstanding way. CONCLUSIONS: The productivity trends provided an indication of the greater scientific interest of physical therapy in aging as a line of research. Collectively, the data indicated that physical therapy-specific journals are being consolidated but non-specific are still a significant research source, and that a fundamental element of their research includes exercise and movement.

Subsequent full publication of abstracts presented in the annual meetings of the Spanish Society of Cardiology.

INTRODUCTION AND OBJECTIVES: The Spanish Society of Cardiology holds an annual national meeting with a large number of presentations but the number of full-text publications resulting from these presentations and the journals accepting these manuscripts is unknown. This study aimed to identify the full-text publication rate of accepted abstracts and to analyze the bibliometric features of subsequent publications. METHODS: We randomly selected a sample of 300 oral presentations at the meetings of the Spanish Society of Cardiology in 2002, 2005 and 2008. Subsequent publications were identified through the Science Citation Index-Expanded, Scopus, Índice Médico Español, and Índice Bibliográfico Español en Ciencias de la Salud. RESULTS: Of 300 abstracts, 115 resulted in 147 full publications, representing a publication rate of 38.33%. The meeting with the highest publication rate (43%) was held in 2005. The subject category with the highest number of publications was Pediatric Cardiology/Congenital Heart Disease (58.8%). Time to full publication was usually 2 years (30.61%). Articles were published in 57 journals. The journals publishing the highest number of articles were Revista Española de Cardiología (n=55; 37.41%) and the European Heart Journal (n=8; 5.44%). CONCLUSIONS: The high percentage of articles published in the upper half of journals listed in Journal Citation Reports under the category of cardiac and cardiovascular system (83%) can be taken as an objective quality indicator of the results presented at these meetings. However, more than 60% of the abstracts did not result in full publications, thus depriving the scientific community of potentially interesting results.

Publicaciones derivadas de las comunicaciones a los congresos anuales de la Sociedad Española de Cardiología / Subsequent Full Publication of Abstracts Presented in the Annual Meetings of the Spanish Society of Cardiology

Introducción y objetivos. La Sociedad Española de Cardiología celebra anualmente un congreso nacional en el que se presentan numerosas comunicaciones. Sin embargo, se desconoce si posteriormente se publican como artículos y en qué revistas. Nuestro objetivo es identificar el grado de publicación de estas comunicaciones y analizar sus características bibliométricas. Métodos. Se seleccionó aleatoriamente una muestra de 300 comunicaciones presentadas de forma oral durante los congresos de 2002, 2005 y 2008. La identificación de los trabajos publicados se realizó mediante búsqueda en las bases de datos Science Citation Index-Expanded, Scopus, Índice Médico Español e Índice Bibliográfico Español en Ciencias de la Salud. Resultados. De las 300 comunicaciones, 115 derivaron en 147 artículos publicados (el 38,33% de publicación). El congreso que obtuvo un mayor índice de publicaciones fue el de 2005 (43%). El mayor número correspondió al área de cardiología pediátrica/cardiopatías congénitas (58,8%). El mayor porcentaje de trabajos se publicó a los 2 años de la celebración del congreso (30,61%). Los artículos se han publicado en 57 revistas, de las que han pblicado el mayor número de artículos Revista Española de Cardiología (n = 55; 37,41%) y European Heart Journal (n = 8; 5,44%). Conclusiones. El alto porcentaje de artículos publicados en revistas de la mitad superior de la categoría Cardiac and Cardiovascular System del Journal Citation Reports (83%) se puede considerar un indicador objetivo de la calidad de las comunicaciones presentadas en estos congresos. Que más de un 60% de las comunicaciones no se publique priva a la comunidad científica de unos resultados potencialmente interesantes (AU)

[An analysis of Spanish scientific productivity in substance abuse according to disciplinary collaboration]. / Analisis de la produccion cientifica española sobre abuso de sustancias en funcion de la colaboracion entre disciplinas.

OBJECTIVES: The analysis of productivity and disciplinary collaboration patterns for Spanish published scientific research in the field of Substance Abuse (2001-2005). METHODOLOGY: From institutional affiliations we identified and quantified disciplinary participation in papers indexed in the IME/Indice Medico Español, ISOC/Indice Español de Ciencias Sociales y Humanidades, SCI-Expanded/Science Citation Index-Expanded and SSCI/Social Sciences Citation Index databases. RESULTS: A total of 31 disciplines and specialities were identified in ISOC, with 8.6% of documents in collaboration between them; 55 medical specialities were identified in IME, with 10.89% of documents in collaboration between them; and 62 specialities were identified in SCI-Expanded, with 41.68% of documents in collaboration between them. CONCLUSIONS: a) Substance Abuse, Psychology, Psychiatry, Epidemiology-Preventive Medicine and Public Health and Pharmacology are the disciplines and specialities that present the highest productivity. To these can be added, in papers published in foreign journals, specialities such as Biochemistry-Molecular Biology, Neurology and Neuroscience; b) Papers published in Spanish journals indexed in SCI-Expanded and in papers published in foreign journals present much higher collaboration indexes between disciplines and specialities; c) The main collaborations between specialities are those between Substance Abuse, Psychiatry and Psychology. To these can be added, in the case of journals indexed in SCI-Expanded, those between these specialities and Pharmacology, Neurology and Neuroscience.

Coauthorship networks and institutional collaboration patterns in reproductive biology.

OBJECTIVE: Reproductive biology is a highly productive area. By analyzing papers published in the major journals in the period 2003-2005, the collaborative patterns were characterized. DESIGN: Original research papers published in 2004 in the journals included in the first quartile of the category "Reproductive Biology" of the Journal Citation Reports (2005) were selected. A bibliometric analysis was carried out with the information obtained, thus building up the networks of coauthorship and institutional collaboration. RESULT(S): A total of 4,702 papers were analyzed, 96.75% signed in collaboration by two or more authors, the authors per paper index being 5.24; 73.73% of the papers were collaborations between institutions. The U.S.A. and the U.K. headed the absolute productivity ranking in number of papers, and adapting the data with respect to the population, Israel, Australia, and other European countries, such as Finland, Belgium, Sweden, and The Netherlands, had notable contributions. CONCLUSION(S): We identified the networks of authors who publish in the journals with the greatest impact factor. Only some of the most productive institutions have consolidated collaborative relationships with other institutions. We identified the scientific "isolation" of some countries which, although their productivity is high, have a small number of international collaborations.

[Gender analysis of Spanish scientific publications in the area of substance abuse in biomedicine 1999-2004]. / Análisis de género de la producción científica española sobre drogodependencias en biomedicina 1999-2004.

BACKGROUND AND OBJECTIVE: Concern for encouraging gender equality makes it one of the high priority spheres of action for governments and organisations responsible for instigating scientific policies, with particular importance being placed on including the gender variable in evaluative analyses of scientific and technological activity. A comparative study was made, broken down by gender, of the scientific output of Spanish researchers with a high production in the field of substance abuse. MATERIAL AND METHOD: We identified the gender of 338 authors who had published more than four different articles during the period from 1999-2004 and which were indexed in the IME/Indice Médico Español and the SCI/Science Citation Index databases, making a comparative analysis of their output and collaboration patterns, based on the gender variable. RESULTS: In the area of substance abuse, of those with the highest output (> 9 papers), 70% were men compared with 30% women. Among the average producers (5-9 papers), 57% of the authors identified were men and 43% women. Statistically significant differences were observed between men and women with the highest output with regard to the number of published works and those with whom they had collaborated. CONCLUSIONS: There is no gender equality in the area of substance abuse, particularly when considering the top researchers. It is essential to make in-depth studies that evaluate scientific output, broken down by gender, in order to adopt the necessary corrective measures to eliminate the disparity between men and women.

Análisis de género de la producción científica española sobre drogodependencias en biomedicina 1999-2004 / Gender analysis of spanish scientific publications in the area of substance abuse in biomedicine 1999-2004

Fundamento y objetivo: La preocupación por favorecer la igualdad de género constituye uno de los ámbitos prioritarios objeto de atención por parte de los gobiernos y los organismos gestores de las políticas científicas, destacándose la importancia de incluir la variable del sexo en los análisis evaluativos de la actividad científica y tecnológica. Se realiza un estudio comparativo desagregado por sexos de la producción científica de los investigadores españoles de elevada productividad en el área de las drogodependencias. Material y método: Se han identificado el sexo de los 338 autores que han publicado más de cuatro artículos distintos durante el período 1999-2004 indexados en las bases de datos IME/Índice Médico Español y SCI/Science Citation Index, analizando comparativamente su productividad y patrones de colaboración considerantdo la variable sexo. Resultados: Entre los grandes productores (> 9 trabajadores) del ámbito de las drogodependencias predominan los hombres (70%) frente a las mujeres (30%). Entre los productores moderados (5-9 trabajos), el 57% de los autores identificados fueron hombres frente a un 43% de mujeres. Se han observado diferencias estadísticamente significativas entre hombre y mujeres en los grandes productores en cuando al número de trabajos publicados y personas con las que han colaborado. Conclusiones: En el área de las drogodependencias no existe una igualdad de género, especialmente cuando se considera la élite de la investigación. Resulta fundamental profundizar en estudios que evalúen de forma desagregada por sexos la productividad científica para acometer las medidas correctoras necesarias que permitan alcanzar la igualdad de género

[Impact factor of the Spanish medical journals]. / Factor de impacto de las revistas médicas españolas.

BACKGROUND AND OBJECTIVE: The 2001 edition of the Journal Citation Reports (JCR) includes only 13 Spanish medical journals. The impact factor (IF) of the rest of Spanish medical journals is unknown. The aim of this study is to determine the IF of the main Spanish medical journals, taking also into account the references from journals not covered by the SCI. MATERIAL AND METHOD: A set of 87 Spanish medical journals was selected from the national database IME and other international databases. All citable articles published in these journals in 2001 were analyzed, extracting their bibliographic references to articles published in 1999, 2000 and 2001. The indicators obtained for each journal were the number of cites, the IF and the immediacy index. RESULTS: Among the 87 source journals, 74 were not included in the JCR. From them, 5,388 bibliographic references were examined, identifying the journals cited. Final indicators were obtained adding these results to the ones obtained by using the Science Citation Index. The most cited journal was Medicina Clinica (768 cites), and the highest IF were attained by Histology and Histopathology (IF = 1.866), International Journal of Developmental Biology (IF = 1.654) and Medicina Clinica (IF = 1.125). CONCLUSIONS: This work has permitted to obtain the IF of 87 Spanish medical journals. Already detected in previous works, the leadership of the journal Medicina Clinica in Spanish medicine is confirmed. Spanish medical journals published in English have received a small number of cites from the ones published in Spanish. A low impact factor is not necessarily related to lack of quality, merit or relevance.

Factor de impacto de las revistas médicas españolas / Impact factor of the Spanish medical journals

FUNDAMENTO Y OBJETIVO: En 2001 sólo 13 revistas médicas españolas estaban incluidas en el Journal Citation Reports, por lo que se desconoce el factor de impacto (FI) del resto de revistas españolas. El objetivo es determinar el FI de las principales revistas médicas españolas, teniendo en cuenta las citas procedentes de las revistas no incluidas en la cobertura del Science Citation Index. MATERIAL Y MÉTODO: Se analizaron las referencias bibliográficas de 1999, 2000 y 2001 de los artículos citables publicados en 2001 en una selección de 87 revistas médicas españolas incluidas en la base de datos nacional Índice Médico Español y en alguna otra base de datos internacional. Se calcularon el número de citas, el FI y el índice de inmediatez de cada revista. RESULTADOS: Se analizaron 5.388 referencias bibliográficas procedentes de 74 revistas fuente o citadoras no incluidas en el Journal Citation Reports y se identificaron las revistas citadas. A estas citas se añadieron las que cada revista había recibido en Science Citation Index. La revista más citada fue MEDICINA CLÍNICA, con 768 citas, y las de mayor FI fueron Histology and Histopathology (FI = 1,866), International Journal of Developmental Biology (FI = 1,654) y MEDICINA CLÍNICA (FI = 1,125). CONCLUSIONES: Este trabajo ha permitido obtener el FI de 87 revistas médicas españolas y confirma los resultados obtenidos en trabajos anteriores que mostraron el liderazgo de MEDICINA CLÍNICA en la medicina española. Las revistas publicadas en inglés han recibido pocas citas del resto de las españolas. La falta de impacto en algunas revistas no está necesariamente relacionada con su falta de calidad, mérito o relevancia (AU)
